The Next Subaru WRX STI Will Almost Definitely Be a Hybrid

Subaru hasn't directly said the new STI will be a hybrid, but based on recent comments, it sure sounds like that's exactly what's going to happen.

Back in 2015, we heard a shocking rumor that the next Subaru WRX STI would be a hybrid. At the time, there were no direct quotes from Subaru executives, so the report from Australia’s Motoring could have been pure speculation. But now it sounds like that report was pretty accurate.

Speaking to AutoExpress, Chris Hawken, Subaru’s U.K. marketing director, said “[Subaru’s Global Platform] has been designed to take hybrid and electric.” While we knew that part, it’s the next thing he said that was more interesting. “That is the way STI is going,” said Hawken. That’s not necessarily confirmation, but it sure sounds a lot like Subaru plans to make the new STI a hybrid.

As for why Subaru would potentially electrify the next STI, Hawken said it has to do with emissions requirements. “We are definitely working on downsized turbo engines,” he told AutoExpress. “With Euro 6c coming in next September, cars like the existing STI have to stop. By 2019 and 2020 manufacturers have to show a massive drop in CO2. The future is petrol, hybrid, and electric.”

Again, Hawken didn’t come out and say, “The next Subaru WRX STI will be a hybrid,” but reading those comments, it’s hard to imagine a Subaru producing a new STI that isn’t a hybrid. That may upset some STI purists, but as we’ve seen with performance hybrids like the McLaren P1 and the Porsche 918, with the right setup, hybrids don’t have to be boring.

Hybrid or not, it will still be several years before we see the new STI. Subaru recently said the new WRX and STI won’t arrive for at least two and a half years.
